T aZZ'wwrlzI it may concern;

Be it vknown that l, GOODRICH Q. Lewis, e citizen of the United States, residing et lJVheeton, in the county' of Dopage and State of illinois, have invented. e certain new end useful improvement inl Refrig extended beyond the opper ere-tor Cer Door Locking Mechanism, of which the following is s full, clear, concise, and exact description, reference being had to the 'accompanying drawnes, forming n part of this specification. A

This invention relates to improvements in 4refrigerator oar door locking mechanism.

. In; loading and unloading refrigerotor f eers near platforms, it lies been found niet much difficulty nos been encountered in swinging" the door open when the cer is adjacent-the platform, for the reason that the platform is generally constructed. on e level with the Hoor level of. tnecer in order to facilitate trucking. 'in such circumstances, alie door locking shaft-having lle `crank arms er `the ends thereof necessarily end lower edges of tne door, encounters the platform, the door cannot be opened unless loe pleo end- Specceton of Letters Patent'.

remorse nos es, vlere,

in said drawing, l0 ldemnos the frame members of the. cer to which the doors ll :rigid 12 ere pivoeelly connected, es ley hingesli alle doorjl Acarries the latch MC for the lever 11 y 1 n or erin lo-pivotally conneced to ine shaft A, es etl fend which the 'share is operated, ,l

'The shaft A comprises .en 'intermediate 6K5 in the endsI of lie inernlier l s', the latter lseing 70 secured ,to the orenl members i8 by ,rivets or `other suitable fastening; devices iol-20.

Esch crank member 18,' Wiiioo rnfy bein the y-forin of e casting., en oise-ell orenkpinl x form is chopped away to provide tne 'necessary clearance for the lower ends of the door 'operating shafts. Not only is this e. groin?v but considerable .time and inconvenience, labor is lost in chopping sway the platform to provide the olea-rance for the sliefts, and the platforms are seriously injured.

T he olojecJ of my invention is to provide means in connection with the 'rnost common form of refrigerator our door operating' shaft Which Will overcome the objections above indica-ted, and to provide suolo Ineens atpractically no additional expense.

In the drawings forming e pero of this specification, Figure l is 'a side elevation of e portion of e refrigerator cer end door, showing improvements in therewiln-rhe doors losing in closed position; Fig. 2 is e horizoniel sectional View snbstanislly on line 2 2 of Fig. i, and showing one of the Vdoors in partly opened position in dotted lines; Fig. 3 is en enlarged vertical sec'ionel View taken substantially on line 3--3 of Fig. l; and Fig. is a View somewhat similar to thas of Fig. l,

but showing the door carrying lle shaft in connection 4 and an elongated journal 2:2, one journal por 'i5 tions @w22 being mounted in snileble loserings S33-23 secured so. she door l2. 'es clearly shown in Figs. i, 3 end 4l, lie 310er nels :areconsiderably longer tlienlie loesringsQ- 5% miti-ed lonv'iudinsl movement therein. vThe crenlrpins 2l-2l engege and coperee with keepers secured to the upper and lower members of the, door freine, one of seid vkeepers As shown in seid figure, escli keeper 2li is provided with tivo, snnulerly arranged, com

feces 25 end 26, ne letter cooperating with l tlie omni; pins 2l in closing the doors, and

the former cooperating with the crank pins 90 to open lie floors, 'in s manner Weil under stood; Also mounted on the door i2, loetween shi-ft end the free edge of the door and oelow #ghe lever l5 when lie latter is in position shown in Fig'. l, is e 95 'bracket 27 having a curved bearing portion 28 on the upper end `thereof, seid bearing 28 serving' es ey fulcrnm for the l5 to lift the siieft A verticellyeo elle' position shown in Fig. 4. l

ln opersins elle device, the lever 3.5 is first released ley moving 'the lstoli lli., und the slmfe A relisted merely i8()` degrees, whereupon the door 12 will be moved ont to the dotted lines in Fig. 2. 'in this position 'of the shell; A, lie osei' crank pins 2lb-21 extend over the adjacent edges of the door o i?. so that falle sheftfik cannot, in this osi-` non, ne moreel 'vertioelly up end own; .uy

i3. .Thedoor l2 carries opereing shaft' A, cies riloed more in detell 'liereinefzen and so so, that *Joe shaft A is pen being shown in pien in. Fig.

through en ero epproxiposition shown' in wo -thereforeit is necessary to swing the shaft A back through approximately an are of '4180 degrees7 but Without engaging the crank pins .2l witlirthe keepers 24:.` When swung back to this position, the lever is then pressed downwardly, and on account of A the bracket 27 serving as a'fulcrum, the

shaft Ar will be raised vertically suiiciently for the lower crank pin 2l to clear the adja cent platform indicated in Fig. 3 at 29,

'whereupon the door 12 can beA swung out over the platform without difficulty. In 'moving the shaft A vertically, in the manner hereinbefore described," the shoulder 30 on the upper crank member 19 will engage the under side of the bearing 23 to limit the .scribed will take stood. y.

yamount of such movementi In closing the doors, the reverse of the operations just deplace, as will be underpri g a 4shaft rotatably mounted on said door, vshaft having crarr pins at the ends of meer operating mechanism therefor com.

thereof'normally extendin above and be- I low the door, said shaft ingklongitudinally slidably mounted relatively to said door whereby the lower lcrank pin may be moved to a position flush with or above the lower edge of the door to thereby permit the door to be swung outover a platform or the like on a level with the lower edge of the door.

2. The combination with a hinged door, of a door operatingmechanism comprisin a shaft' rotatably and longitudinally sli ably mounted on said door, means for shifting said shaft longitudinally of the door, said means including a lever pivotally connected to the shaft, and a fulcrum bracket secured to the door with which said lever is4 adapted tov coperate.

3. In a refrigerator car, the combination with a hinged door, of a shaft mounted on said door, said shaft having journals at each end thereof, bearings mounted on said door Within which said journals are rotatably and longitudinally slidably mounted, a lever pivotally connected to said shaft, and a fulcrum bracket secured to said door and below the normal position of said'lever, Said bracket serving as a fulcrum for said lever when the latter is swung rdownwardly in' thereby lift the shaft vertically.
